Points To Consider When Replacing A Walk-in
So the frozen food in your walk-in isn’t so
frozen anymore and your door has so much
ice accumulated around it that it won’t open?
Might be time to look at a replacement. But,
just like any major purchase, there are lots
of factors to consider and you want to make
sure you get your money’s worth – especially
in today’s economy. Here’s a rundown of
some of the main points to keep in mind.
1. Look For The Signs
There are several telltale signs that your
walk-in is getting ready to bite the dust:
• Sagging doors allowing outside air in
resulting in ice buildup on the evaporator
coil
• Panels separating from the foam or
“delaminating”
• Panels that are damaged from use or
abuse
• Panel seams on the interior of the walk-in
walls or ceilings that have condensation
or frost built up on them. This build-up
signifies that the seal is no longer adequate
and air is leaking thru the seams. If the
door and frame are the only place this is
occurring, a retrofit door assembly could
be the answer (see the sidebar on page 2).
2. Consider The Basics
Before replacing a walk-in, here are some
points to think about:
• What will be stored in the walk-in?
Depending on an item’s density and
temperature, it may take longer to pull
down to the correct temperature and
a larger refrigeration system may be
necessary to compensate.
• What about the door(s)? Doors receive
most of the abuse of day-to-day traffic.
If doors are frequently opened and
closed, you may need a heavy-duty door.
Automatic closing devices like cam-lift
hinges and a positive door closer are also
required so that the door isn’t accidently
left open. If it’s necessary to see inside the
– Continued on page 2
Daily usage, type and weight of product stored, and future
expansion plans are a few considerations to keep in mind
when replacing a walk-in.

walk-in, you will need a view window.
Kickplates on the door and inside the
walk-in are also helpful in preventing
damage. Strip curtains are another useful
option that will help block outside air.
• Don’t forget the floor. Consider the weight
and frequency of traffic to determine what
type of flooring you’ll need. If you’ll be
using heavy-loaded carts or heavy shelving
inside, you may need a reinforced floor or
even a structural floor. If your walk-in will
have floor panels, an interior or exterior
floor ramp makes for easier access.
• Plan for the future. Will space requirements
be increasing soon or will it be necessary
to move the walk-in some day? Look
for panels that are cam-locking (most
are these days). Cam-locks make it easy
to dismantle and move your walk-in or
expand it should you need to.
• Get the whole package. Can the
manufacturer supply both panels and
refrigeration system? Getting both from
one source can save a lot of time and
headaches. Also, remember that on larger
projects, you may need help with walkin and system design. Make sure your
supplier or manufacturer has this
capability.

the most energy efficient (factors
that pay for themselves over time). Also, keep
in mind polyurethane panels meet or exceed
all the efficiency requirements of the Federal
Energy Independence and Security Act of
2007. Additionally, the foam insulation used
in polyurethane panels is green friendly and
is completely CFC/HCFC free.
Maximum use of storage space is another
factor to consider. Polyurethane panels,
because of their greater efficiency, can
be much thinner and still meet R-factor
requirements. As a comparison, it would
take approximately 8 inches of polystyrene
or 33 inches of solid wood to equal the
insulation value of 4 inches of polyurethane.
Thinner panels equal more usable space.
4. Pick The Right Finish
Panels are offered in a wide variety of
finishes on both the interior and exterior.
One of the most popular finishes is stucco
galvalume because its embossed pattern
helps hide scratches, dents and blemishes
that are inevitable over time. Other options
include smooth stainless steel, galvanized
steel and stucco or smooth aluminum.
5. Choose A Type To Fit Your Budget
There are several types of walk-ins available
depending on your budget. Custom designed
walk-ins can be configured in practically any
size or shape to suit your needs but may cost
more due to design time.
Quick ship walk-ins are pre-configured
sizes that typically ship in five business
days. Because they are stock models, you
may be able to save money if you find a size
to fit your needs. Quick ship models come
with either a remote refrigeration system
or with a packaged system containing the
condensing unit and evaporator coil in one
housing.
Factory pre-assembled walk-ins offer
the maximum convenience. These models
ship from the factory completely ready to
set in place. All that’s required is to provide
electricity at the job site.

Knock Knock . . .
A man went to answer a knock at his door and upon opening it, found a huge cockroach.
“Yes?” asked the man. “What can I do for you?” Instead of answering, the cockroach
slapped the man and ran off.
The next night there was another knock at the door. When the man answered, he
found the cockroach once again. This time, the cockroach kicked the heck out of the
man and ran off once more.
On the third night, there was a familiar knock at the door. The man cautiously opened
it and no sooner did he peek out than the cockroach bit him and took off.
The man was so worried about the bite that he called his doctor and told him the
whole story. “What is going on?” the man asked.
“Ah, yes,” the doctor said. “There’s a nasty bug going around.”
I Resolve To Make Some Resolutions
Time for some New Year’s resolutions? Here are some silly ones:
• Stop sitting in my living room all day in my pajamas. Instead, I will move my
computer into the bedroom.
• Figure out why I really need 12 e-mail addresses.
• Think of a computer password other than “password.”
• Stop sending e-mail, text messages, and instant messages to people when I’m already
on the phone with them.
• Spend more time with neglected children—my own.
Faster Than A Speeding Bullet
A state trooper noticed a car driving along the highway very slowly. His radar clocked
the vehicle at 22 mph. The trooper, worried that the driver might be in trouble, turned
on his siren and brought the slow-moving car to a stop.
The driver was an elderly man. In the back seat sat two old ladies, both trembling
with fright. “What’s wrong, officer?” asked the driver. “I was driving the speed limit.
It was on the sign back there.”
The trooper realized what had happened. “Sir, that wasn’t the speed limit sign, that
was the route number. The speed limit is 65. You’re on Highway 22.”
“Oh,” the man said with a nod. “Sorry about that.”
The trooper looked into the back seat. “Are they all right?”
“Those are my sisters,” said the driver. “They’ll be fine. We just got off Highway
175.”

Partners In Success
Utah Food Bank & Commercial Kitchen Supply
Salt Lake City, UT
Commercial Kitchen Supply (CKS) recently completed
installation of one of the largest refrigerated foodservice
warehouses in their state for the Utah Food Bank. The
cooler/freezer combination stands approximately 180
ft. long x 38 ft. wide and 20 ft. tall.
“It was the height that could have been a problem,”
states Keith Eubank, vice president and co-owner
of Commercial Kitchen and Supply based out of
Centerville, UT. “We needed a seamless panel and
Master-Bilt is one of the only manufacturers that offers
a superior 20 foot tall one-piece panel.”
Opened in 1904 the Utah Food Bank had outgrown
its food storage capacity, turning away some three
million pounds of food a year due to lack of freezer
space. Ten years ago, the organization was distributing
nine million pounds of food annually whereas today
they are distributing over 19 million pounds of food per
year. This increase resulted in the move to a new facility
that more than doubled cold storage capacity.
The new refrigerated food storage space consists of
an approximately 60 ft. x 38 ft. cooler and 101 ft. x 38 ft.
freezer with a 19 ft. x 38 ft. staging area in between. The
plans called for the warehouse to be installed between
pre-existing columns.
“The difficultly with this installation was not only
working around footings, but we had to make sure
the floor of a freezer that big would not freeze,” says
Eubank.
CKS turned to Master-Bilt, who engineered a
seamless innovative solution. “We dug out the floor
and inserted a heating system to keep moisture from
under the freezer,” says Eubank. “It is all the process
of figuring out the challenge before you build the box.
Master-Bilt stands up to their projects and builds their
own refrigeration so you know you are partnering with
the right team.”
CKS also installed two additional 11 ft. x 12 ft. MasterBilt walk in cooler/freezers in the kitchen for the food
bank’s cooking needs. The units were equipped with
a Master-Bilt remote refrigeration system for energy
efficiency.
The project needed to be completed in time for the
busy holiday season. “Master-Bilt was right on track
and accommodated our needs to help with such a
wonderful community outreach project,” concluded
Eubank.
Measuring 180 ft. long x 38 ft. wide and 20 ft. tall, the Utah Food Bank’s
new refrigerated foodservice warehouse is one of the largest in the state.
